Lrl from Italy

[FrancoItaly]

I Think that with Franco Xtal LRL , Lucky frequency can be is with 9.736,305 Mhz . ;)

According to my experience my lrl works with these frequencies: 2.8Mhz (CD4046 version) - 3 - 4 - 6 - 8 - 10Mhz. It is possible that with high frequencies, for example 9 or 10MHz, the sensor stage amplifies more, since TR3 and TR4 are in practice a high pass active filter, through the capacitors placed between emitter and ground.

[humhum]

Hi Franco, this is part High Freq. from main Resonant Frequency of Gold. But here problem is that max. operation Output Freq (OSC) of cd4046 is up to 1.6 Mhz. (Datasheet)

If I not know wrong OSC of 4046 + input Freq OSC from Stylus Antenna make Mix and giving ference freq for Output (for example 1Khz), so like Radio mixer.

If is so OSC from CD4046 not will High Frequency 9 or 10 Mhz .

There are 2 versions of my lrl, one is with CD4046 and it works (in my case) at 2.8Mhz, it is not convenient a higher frequency (over 3Mhz absorbs too much), however with the normal type it is not possible to go further, but it is not necessary. The version with the quartz, as already mentioned, can work from 3 to 10Mhz. The TR2 stage is called mixer, but not in the sense used in radio receivers, in fact here there is not a frequency conversion (we would need very wide signals and here is not the case), but rather an amplitude modulation on the contrary, in fact the signal to lower frequency (for example 8Mhz) is modulated (I would say almost disturbed) by the much higher frequency signal coming from the antenna (about 100Mhz). Regarding the frequency of resonance of gold I do not think it is possible to tune my lrl, also because you first need to know the value of this frequency, if it exists.

[humhum]

I am not sure ,but with your Tr first version if we use Xtal with 9.xxxxx Mhz can be will is possible.

[FrancoItaly]

I am not sure ,but with your Tr first version if we use Xtal with 9.xxxxx Mhz can be will is possible.

The only practical way to check if there is a specific frequency for gold is to try different frequencies. However, as I have already said, we must keep in mind that the sensor stage is practically a high gain high pass filter, therefore it amplifies the frequency of 9MHz more than a 4MHz frequency, for example. When using the 4MHz frequency, the value of C13 / C14 must be increased to achieve the same gain. Or you can increase the gain in the stage display.

[Haydar]

What should be the appropriate antenna length in the terrain?

[FrancoItaly]

What should be the appropriate antenna length in the terrain?

In the range 30/40cm, more length=more sensibility.

[Haydar]

Is it possible to make metal distinction by measuring frequency?

[Haydar]

What does it mean when the receiver voltage rises or decreases while roaming the terrain? In some areas, the voltage rises, and in some regions, I noticed that the receiver voltage decreased.

[FrancoItaly]

I never checked if the signal decreases in some locality, perhaps it depends on the type of terrain. If the gain is excessive in addition to the compass effect, the sky effect also appears, ie a signal appears tilting the lrl downwards or upwards.

[FrancoItaly]

Is it possible to make metal distinction by measuring frequency?

If you mean the frequency of the quartz oscillator I think it does not affect the sensitivity to a certain metal, if you refer to the frequency of the signal from the antenna I do not know, it is not very easy to measure, you can vary the frequency of L1 / C10 and check if the sensitivity to different metals changes.

hi to all freinds
hi franco
What is your opinion about this design pcb 8mhz v.r?
I could not get the result from previous designs

[FrancoItaly]

It is difficult to judge. To avoid self-oscillations I prefer to use a pcb only for the sensor stage (double-sided type), with the components welded on the upper face and with the lower face connected to ground. Otherwise the risk is that the stadium oscillates even with a low gain. Furthermore it is better to set up the sensor stage when its output is still not connected to the display stage.

[Dubulumach]

Get out one preamplifier stage and lower your gain as much as possible but still enough to detect the phenomenon, while cut sky/ground effect.

I will give you one idea. Add several different oscillator stages besides original 8MHz, for example 1MHz, 20Mhz, 100 MHz, and mix very small oscillator's output amplitude on the base of 1st transistor. On this way you will have very wide band detection.Amplitudes must be very low to avoid oversaturation of preamplifier, interferation and slope eadge modulation.Also good narrow band pass filter should be added after amplitude detector.

Interesting project but need a lot of mods.
All credits go to Franco Italy.

NOISE IS YOUR FRIEND becuase can help you to find a lot of gold coins. :)

The idea seems good, but difficult to apply on the sensor stage, which in practice is an active high pass filter preceded by a sort of mixer (TR2). In practice the gain is optimized for a certain frequency, a separate sensor stage should be built for each frequency. In my opinion the frequency of the oscillator is not very important, let's not forget that the phenomenon comes from the antenna and is filtered by L1 / C10 and probably there is a carrier of about 100Mhz which is modulated by the phenomenon. On the basis of TR2 two signals arrive, the phenomenon and the oscillator signal. This is not frequency conversion, it is not a linear mixing, it simply increases the amplitude of the oscillator signal. The fundamental requirement for the operation of my lrl is that there is some transmitter in the 100Mhz band, for example private radio stations or satellite broadcasters.

[mustefa ubram]

hi franco
Franco I corrected according to your guidance

[FrancoItaly]

It seems to me that it is fine, but the definitive proof is the good functioning. I must admit that it is not easy to set up, in this period I am working on a sensor stage of a lrl that I realized long ago, its sensitivity is low, while revealing the phenomenon. I think the reason is the low beta of the transistors but unfortunately where I am I don't have the possibility to try other transistors. I have yet to try removing R10 / C13 to get the maximum gain.

[sakher]

Hello my frinds
where is the best points on the circuit to test frequency?

[FrancoItaly]

If you mean the input frequency of the sensor stage you can only calculate it theoretically with the values of L1 / C10 + about 10pF of the parasitic capacitance of the TR2 base / emitter, or you can use an external oscillator and check for what frequency there is a variation to the out of the sensor stage. However the most important thing is to establish which is the best frequency on the test field, C10 can be 10 or 15 or 20pF, or nothing, only the base / emitter capacity.

Thank you Mr.Franco, Is there required frequency range that i must measure it ?

[FrancoItaly]

Thank you Mr.Franco, Is there required frequency range that i must measure it ?

There is no particular frequency required, it is just a matter of finding the best value for C10. I found that my lrl (in my country) also works well with L1 = 2 turns and C10 = 10pF, or L1 = 3 turns and C10 = 22pF. I think that the phenomenon emits in the range 80 - 120Mhz and that it is important that there are radio or TV stations that transmit in that frequency range that act as a "stimulus". This could explain why my lrl (but I also believe others) does not work in certain areas.

[sakher]

Thank you very much :)

Have you tried an antenna amplifier on the test field?
If your answer is yes What has Results?

Hello dear franco:)

If your answer is yes What has Results?
Thanks for your patience.

In my case the sensitivity has increased by about 20%. The main advantage is that the antenna amplifier compensates for the fact that the sensor stage has not been adjusted for the highest possible sensitivity.

[taher5739]

Sensitivity for gold or silver has increased, or both?
I want to know if adding the filter to the antenna amplifier section ,
Can make a distinction for copper or gold?
i wish you success in life:)

[havoc88]

Dear Franco which coil is right? or very sensivity

1. or 2. picture?


There is no "right" or "wrong" coil at least if both of them have three turns of wire plus there is no special reason to have vertical or horizontal position, only practical workspace on your pcb.

[k.hasanzade]

Dear franco
Thanks first for the design of the circuit that you design
I have a few questions
1. What is the reason for changing the circuit coil?
2. It is better not to install the first coil vertically and the second wire sheet horizontally؟
3.What is the new circuit calibration method?

I buried silver and gold objects in my test field. Silver, buried for about 2 years, responds well, while gold, which has been buried for less than a year, responds little. In my previous test field (not here but in Italy and that I no longer have available) instead the gold responded well and it was a thin bracelet.
The amplifier antenna increases the sensitivity for all metals and I do not believe that the addition of a filter can be useful, however I did not do this test.

[FrancoItaly]

I agree, the coil is part of a resonant circuit and there is no risk of self-oscillation. In fact, if there were two coils belonging to two different stages and tuned to the same frequency, there would be this risk and placing the two coils perpendicular to each other would reduce mutual coupling.

I refer to the antenna amplifier not to the antenna amplifier 2 which I suggest to build after the antenna amplifier.

1. The amplifier antenna increases the signal received from the antenna (let's call it phenomenon) and increases the total gain of the sensor stage which in some realizations may not be sufficient.
2. With the addition of the amplifier antenna there is always only one coil which is only moved.
3. The calibration method remains the same, only you have to do so before mounting the antenna amplifier. Subsequently the amplifier antenna is mounted and on the test field the 4.7K trimmer is set for maximum sensitivity.

How to adjust potentiometer settings?

[FrancoItaly]

How to adjust potentiometer settings?

P1 (22K) is the threshold, it must be adjusted to have all the LEDs off, it also acts as a sensitivity control. P2 is the gain control, in the past I advised to change R1 (from 150K to 56K) and R2 (220K to 560K) to have more gain. To have a more precise threshold adjustment I recommend adding RA and RB. Their value depends on the output voltage of the sensor stage. The optimal value is when the first LED lights up with the maximum control.
If it is necessary to decrease RA (for example from 22K to 15K) increase RB (from 22K to 27K) in order to keep the divider value constant (Ra + RB + P1). Vice versa if it is necessary to increase RA.

In practice my lrl is a high gain amplifier for the 8Mhz signal mixed with the "phenomenon". If the quartz oscillator works properly the lack of signal at the output means that there is not enough amplification. Transistors must be of the BC183C or BC547C type or equivalent with a beta greater than 500. The amplification can be increased by increasing the value of C13 / C14 and decreasing R10 / R12. Before doing this you can increase C2 / C3 / C4 which establish how much signal will be amplified, you can only leave C2, or only C2 / C3 so as to have 1pF or 0.5pF respectively. Yes the bottom sideb is connected to ground, it is a screen to reduce the possibility of self-oscillation.

In my first lrl (self oscillating) the lower strips are not needed, in fact the lower screen is used to prevent self-oscillations. I advise against using this version, I made the version with oscillator just to make the lrl less critical to build. One way to trigger the self oscillation is to use a lower strip to connect the collector of TR2 with the base of TR1 or between the collector of TR3 with the base of TR2 via an appropriate (small value) capacitor. In this way two points out of phase of 360 degrees are connected. The only possible advantage of this version is that with it you are sure to have obtained the maximum amplification. As I said in the past this lrl derives from a bug detector that auto oscillated providing a stable signal capable of revealing the "phenomenon".

In previous posts I suggested increasing R2 (from 220K to 560K) and decreasing R1 (from 150K to 56k) to increase the gain. Furthermore, to make P1 adjustment easier, 2 resistors (22K), one on the + 12V side and the other on the ground side should be placed in series with P1. The exact values of the 2 resistances must be found experimentally because it depends on the output value of the sensor stage (connected to the + input). If you increase the value of a resistance, you must also decrease the value of the other, so that their sum is in the range 30 - 50K. The ideal value is when P1 is set to maximum to the right, the first LED lights up and the buzzer sounds.

Hello
Sorry I wanted to send a private message to this user.
After that I did everything I could not clear this text.

[havoc88]

I 've got a problem with the final version of 8MHz Franco's LRL build by Arash.
I've found a route (part) mistake in LM358 port, that's ok, working perfectly now but my main problem is that the TR5 (Q5 in current pcb) output is 3.15v no matter what i do, with crystal on or not.
I've double checked everything. Resistors, capacitors, nothing.

I upload the part that is wrong in pcb for anyone who made it
https://i.ibb.co/VC14scy/correction.jpg


Any idea ?

[havoc88]

OK I found the fault, the silk screen in Arash PCB shows reversed every transistor image but marked correctly in pins -> EBC not CBE. :D I reversed them and now it's working as it should be.

[Arash]

The pcb tested, and making a lot, is fine and works well
Volume is okay, wires need to be properly connected, design is for the volume multi turn, you will replace the wire for the normal volume
It is better for you to read the content written by Mr. Franco

[havoc88]

Mr. Franco and friends.
Everything works perfectly when antenna is directly to base of TR2, it senses electrical signals, compass effect (maybe 99% :D ) but then, when I connect the antenna to the amplifier makes the detector not working at all (always outputs constant max signal and no effect no matter what) like it overdrives everything. Any clues?

The potentiometer must be adjusted for maximum sensitivity, which often does not coincide with maximum amplification. Too much amplification can cause self oscillation.

Thank you for your answer Mr. Franco. I think that I may have a npn with too much hfe for the antenna amplifier, I will replace it now. It's the only thing left. :D

It is possible, but I think it is not necessary, simply by changing the quartz you get different frequencies. I tried 3/4/6/8/10 Mhz and I think that 8Mhz is the best value, even if with the other values the lrl works well anyway.

[Pahom]

Not a bad LTC 6900 chip, but Sinus is still better. The truth is that for some reason the sine on my generator is not clean, the question is a bit with a failure. How to make it clean without failure. According to pick up 33k, 47k and 330pf? A transistor with the letter B but I think that it is not the point.

Varying C1 changes the amplitude of the oscillator, however the waveform is not very important, an amplitude between 2 and 3 Volts from peak to peak is the optimal value. Too high a value would make calibration difficult. Keep in mind that the oscillator does not intervene directly in the reception of the "phenomenon", it only provides a carrier that will be somehow modulated by the phenomenon.

hi i have a question
self oscillation can be exist in display stage or just in sensor stage?

Thanks Franco Italy !!!! I have reached a pure sine wave. All the same, the transistor was the culprit. And the amplitude is 4.32 volts -124.0 ns. I?ll deal with the adjustment of the amplitude to 3 volts.

Hi friends,

I am late answer for so sorry.

Soon


THx Walkman
I have meet Okantex on Whats app and we speak about this project and test
please i have sent to you PVM look it.

[Pahom]

Hi Geo,
The important thing is that there is a signal at the output of TR1, about 2V - 5V, as I mentioned with the quartz disconnected there should be no DC voltage signal at the output, and with quartz connected you need to choose C2, C3, C4 for a DC signal (about 2-5V). The best solution is a double-sided PCB with the lower face connected to ground and with the components soldered on the top face.
Regards
Good morning Franco! It turns out the signal should be on the basis of TP2 2-3 volts. Thank!

Good afternoon Franco! Not clear situation. Redid with one coil 3 turns and an amplifier. Configured the generator at the output of 2.5 volts. I set up a chain of LEDs and lights up at the end of a 470K variable resistor. I connect the amplifier when the antenna is touched, there is no LEDs burning. Even if you wind 4.7k until the first LED lights up, the next one does not light up when you touch the antenna with your hand. For that there is a reaction and the LEDs light up if I touch the battery power with my hand. The top layer is connected to minus. If you turn off the top layer, it reacts to a hand with 10 cm without touching anything.

Hi all !


Franco Italy LRL very sensitive to E field component. It's raw device not useful at dirty terrains with high mineralization. So much false signals. Spurious signals at rusty iron pieces. If you want to dig old nails and iron is good. All targets are yours.


Better build Geo magnetic lrl modification from Andy Flind. Sch. has given by Geo. Hi Geo ! :)

As I told you privately you have to start by making the original version, that is without the amplifier, following the instructions (helps.txt), touching the antenna the signal at the output of the sensor stage (emitter of TR5) must decrease and therefore if set the threshold to turn on the first led, this should go off by touching the antenna.
You speak of a top layer, but it is the lower one to be connected to the minus and this connection is used to avoid self oscillation. First of all, you have to calibrate the sensor stage in order to have the maximum possible amplification, only then can you connect the display stage.

At this point there is an alternating signal superimposed on a continuous voltage, there is no fixed value for good operation, it must be found experimentally. It is necessary to start with the whole cursor towards + 12V (alternating signal = zero) and increase slightly until you have at the X point a signal of about 2 - 3V from peak to peak. Tuning is not easy since the frequency is lower than the 8Mhz version and C13 / C15 may need to be increased. Due to the high gain of the sensor stage, measuring with the oscilloscope at point X could change the working conditions (maybe the sensor stage could auto oscillate). Sometimes it is useful not to ground the oscilloscope.

[abdou2014]

with 4.5V my LRL reacts to the precious metals fresh to 10 cm, it does not react to iron, it react to the spark of a battery 1.5V from 1.2 meter , it react also to a magnet from 80cm . a laptop from 3 meters . is it sufficient ???

I don't know what to answer, I've never done these tests, as I always say the real test is in the field. I still find it strange that it reacts to a magnet.

[abdou2014]

when I move a magnet quickly to 80 cm it detect it, but by approaching it slowly it detected it at 40 cm , it detects precious metals only when the antenna is pointed to the north or south .

You can make a capacitor of a few picofads by twisting two isolated rigid wires about 5cm long, two ends will be the terminals to be welded and the other two will be unconnected. This is an old trick used by radio amateurs.

My lrl is a passive receiver, however I think it is possible (for places where it does not work) to try to add an external stimulus.

I will use the device at a frequency of 60 and try
The device senses the hand from the antenna

[totob]

mr franco, what do you mean by passive receiver?

[FrancoItaly]

mr franco, what do you mean by passive receiver?

By passive receiver I mean that there is no transmitting oscillator. The internal quartz oscillator serves only to provide a kind of carrier which is modulated by the "phenomenon".

https://5.top4top.net/p_14280b06k1.jpg

1 meter for a piece of silver is already a good result, in fact it shows that the phenomenon is detected. I think that the measurements on TR2 are not very reliable and not necessary, the important thing is that there are 4 / 6V on the collector. What is important is to follow the instructions (helps.txt) to get the maximum amplification, then you can act on the display stage to increase the direct current gain.

[Dubulumach]

By passive receiver I mean that there is no transmitting oscillator. The internal quartz oscillator serves only to provide a kind of carrier which is modulated by the "phenomenon".

Hi dear Franco. How do you do ? :)

In fact carrier wave is not electromagnetic in nature. If it would be electromagnetic every prospector with simple fm radio receiver could easy detect the phenomenon.
Reactance of coupling capacitor at 120MHz is almost 4K, amplitude of sinus signal is in uV range at the base of first transistor. High gain amplifier amplify this tiny oscillating signal and at outpute there must be pure sinus signal with several volts amplitude.

Whole secret is in unknown behaviour of P-N junction of first transistor after illumination by phenomenon signal. On some strange way, phenomenon virtual photon energy make additive to effective coupling oscillator energy, boost his amplitude and in same time make phase shift due to parasitic properties of active circuit components. What is the most strangest about phenomenon it could be detected only at several "holes" in EM spectrum. Thise "holes" are empty parts of spectrum where is no artificial emmision but somehow they are connected with non-uniform distribution of earth virtual photons field and also with earth magnetic field.

I'm pretty well and you? I must admit that after so many years I know very little about the phenomenon, however Esteban said that even a common FM receiver, tuned to no station, would reveal the phenomenon. I agree with you that it's on the basis of TR2 (the mixer stage) that the conversion of the phenomenon takes place.

[Dubulumach]

Thank you dear Franco ! :)

I am Ok.

I think nobody in this world knows what the phenomenon is and how it's created, how work.

Here is similar phenomenon, which you can try when come back from Switzerland. Everyone can test but no one can explain how it work.

[FrancoItaly]

All the experiments and improvements are welcome, I have made my lrl public, with all the details for the realization, not only for the ideas of open source, but also to be able to improve it. I believe I have demonstrated that the phenomenon exists, as those who have realized it can testify. Unfortunately, most of the time I am away from my lab, as well as the test field. The phenomenon appears in a vast range of frequencies, from long waves to FM up to infrared, so it is possible to construct lrls that are based on different frequencies. A big thank you is for Esteban, without whom even today we would know very little about the phenomenon and perhaps this forum would no longer exist.

Dear Franco, my device is very stable, it senses when you touch the antenna as it senses 4g internet device from 1,5 meter , I use a sine wave 12 MHz.
Does not respond with the computer !!

With regard to the two resistors 22 k for variable resistance 22 k did not work with me becomes the device operates non-stop

The optimal amplification is that immediately below the appearance of the compass effect. It is a common phenomenon (I suppose) of all the lrls, moving from north to south or vice versa there is a signal of constant amplitude, while in the case of a metal the signal increases approaching while disappearing on the vertical of the target. The maximum sensitivity is in the north / south direction, average in east / west and west / east direction and minimum in the south / north direction.
Does the 12Khz frequency refer to the quartz oscillator? The lrl works with frequencies between 2.5 and 10Mhz, but certainly also with higher frequencies. The sensor stage in practice amplifies the higher frequencies more, in fact C13 / C14 make the stadium an amplified high pass filter, their value must be chosen based on the frequency and the desired gain. In other words with the values chosen for a frequency of 8Mhz if a quartz of 12Mhz is used the amplification is greater. For variable resistance 22 k you mean the adjustment of the threshold?

Dear Franco, I have encountered a problem with a variable resistance 22k, the problem has been removed, the video I put is not for the original device
I did not notice that the oscillator is not connected to the device
Now when you measure the antenna frequency is 8 MHz
I changed the capacitor 13 and 14 to 100 pico, and resistors to 3k
The device does not respond by touching the hand and responds to the TV at a distance of one meter
Possible help to increase sensitivity

[shahrayar]

Why the device sends a wave of 8 MHz
It receives 12 MHz
Why not make the transmitter and receiver the same frequency, or be very close

[shahrayar]

I did not watch well, coil worth 60 nano Henry :lol::lol:
It means a frequency of 120 MHz
How the oscillator responds with this :nono::nono:

My device is not affected only by the hands and a few devices up close
I do not understand
Please some clarification

[shahrayar]

Hi darkman,

The values seem correct, the correct value of sensitivity is a bit less than the beginning of the compass effect. Have you tried this test? If you are unable to have this effect means that there is not enough amplification. This is confirmed by the fact that you are using 6.6pF for C2, C3 and C4, typically this value is about 1pF. Also for the gain of the stage it is the rule that maximum gain is before the stage starts to self oscillate. Controls the gain of TR2, TR3 and Tr4, beta must be 500 or higher, try to lower the value of R10-R12 from 1K to 560 ohms or less. Of course there is also the possibility that the buried metal not issue the "phenomenon."

Best regards
Yes, the solution is to reduce resistance 10 and 12

[shahrayar]

Resistance reduction 10 and 12 did not work
The device has lost its sensitivity
Is there a solution, Sir Franco to sense the compass?

[FrancoItaly]

The sensor stage having a high amplification is very critical, I have always suggested to make a pcb only for the sensor stage, with double face and with the lower face connected to ground, this to avoid the danger of self oscillation. I still recommend making the original sensor stage first, that is without the antenna amp and setting it up. The compass effect and the sky effect appear when the amplification is excessive, but to be sure that the total gain is sufficient the lrl must be able to reveal it. If the sensor stage enters self-oscillation before obtaining the compass effect, then its amplification will be insufficient. The transistors must be of the BC183C or BC549C type or others with a gain greater than 500.

[shahrayar]

That is, a copper plate connected to the ground should be placed under the sensor:)

[shahrayar]

I placed a copper plate below the sensor and connected to the ground
Although the copper plate is about 0.5 cm away from the sensor board
The device senses the metal at a distance of 20 cm
But when the value of the two resistors 10 and 9 is reduced, the device becomes not sensitive:angry::lol:

the copper plate must be adherent and under the sensor stage pcb, it must have the same dimensions as the pcb, the best thing is to use a double-sided pcb.

[shahrayar]

Thank you, Sir Franco
I did it, the device sensed the walls, it sensed the large metals as well, but I didn't try to reduce the resistors R9 . R10
The device senses my hand from about 20 cm from the antenna
But all this sensitivity can be eliminated by changing the resistance 22K

I chose the quartz version because it is much simpler and just as effective, in fact there are fewer components, you can easily change the frequency only by changing the quartz and oscillating more easily.

My lrl operates in the range of 100Mhz, the frequency of the internal oscillator is in the range 2 -10Mhz (approximately) and does not intervene directly in the reception of the "phenomenon". However the only way to verify the goodness of your change is on the test field, with buried metals.

Is this system more sensitive than my original lrl? when the sensitivity is such that the compass effect appears, well this means that it is useless to further increase the gain. As I said before the inside oscillator only serves to create a mixer with the phenomenon. It serves to make sure there is always a stable signal at the sensor stage output, even in the absence of the phenomenon.

[shahrayar]

My dear Franco, it is the original I made it before in this way, but due to the lack of capabilities to measure the signal, I used only simulations, and it turns out that most of these programs are a hoax
But with the new simulation program, I discovered my mistakes
Perhaps you studied in universities and schools, but I did not study in universities and schools, and you know your system from me, I am just learning

As I said before, all tests with TV or mobile phones, however inside a house, are worthless. The only test, to be carried out if possible outdoors, is to touch the antenna and (after adjusting the threshold to have the first LED just lit) check that the LED turns off. This guarantees that all the electronic part of the lrl works correctly. Obviously the final test is in the field.

signal direction east of franco. Range 700-800mt

I don't think my lrl has a range of more than 20/30 meters (as I think most of the others). Are you sure you don't have a compass effect? If the signal remains constant going in that direction it is almost certainly this effect.

[okantex]

But walkman is saying..direction is east.
Not north-south direction
How can it be compass effect
Can bobins' direction have effect

[FrancoItaly]

But walkman is saying..direction is east.
Not north-south direction
How can it be compass effect
Can bobins' direction have effect

If the amplification of the lrl is too large, in addition to the compass effect there is also the sky effect, i.e. lowering or raising the lrl you have a signal, the two effects can be combined making it impossible to use. The lrl is a directional instrument, the maximum sensitivity is proceeding from north to south, the minimum is proceeding from south to north and proceeding from east to west and vice versa the sensitivity is medium. Furthermore, approaching the target, the signal increases but cancels right on the vertical where the target is buried. I find it difficult to believe that a target at 500 m can influence my lrl, to be true it should behave as described above, i.e. approaching the target (i.e. at 500m) the signal first weak and then increasingly strong until it decreases and cancels over the target (500m ahead). My lrl like almost all the others ultimately reveals an electrical or electromagnetic signal and therefore is subject to many disturbances.

[okantex]

So, solution is easy
Another test with same adjustment
But without any target . At another place
İf there wont be change on leds...on east west
Then on south north. Directions.
Then on nort south , by increasing sensitivity if he will see compass effect and lose it by rotating to east south..voila..
Walkman will be right about his claim.

buzzer is working..... circuit is single side pcb..but placed on aluminium case...and also ground ed to aluminium case. so , in a way it should act as double layer..
signal is strong..is it self osilation.. even playing with display stage pots ,it does not change

pcb paths seems good. I could not see any short cuts..
I used metal film resistors..ceramic condansators ,bc183c ,8mhz crystal

take care of yourself , stay at home.. stay away from corona risk factors.
wish good luck to all LRL family.
Okantex

[okantex]

btw , after reading helps...I disconnect 4k7 pot of amplifier stage.. means antenna input is cut.
buzzer was active
so , I also disconnect cristal..but buzzer is still active
entrance of IC1A = out point of sensor stage = is 8,25V
is not this too much... changing 560p to 470 p ..will this help...I feel not...

[FrancoItaly]

Thanks for the good wishes, I certainly do not leave home, also because I am in the risk category (over 65 years of age). 8.5V at the sensor stage output is too high, it means that there is self oscillation. I recommend using a separate pcb for the sensor stage. Try using BC ... B type transistors with less gain, replacing one at a time. The important thing is to set up the sensor stage before connecting the amplifier antenna and keeping the original connections.

[okantex]

no antenna
no cristal..
what can cause osilation? just resistors and condansators
btw .. I placed the pcb abovealuminyum .and made ground connection ..now 2.7V first led is brillient.. second and 3th are blinking

do you still advise to replace transistors

[FrancoItaly]

Yes, try replacing the transistors one at a time. Yes, try replacing the transistors one at a time. Of course C9 must be connected to the antenna during calibration, this is to restore the original conditions without the amplifier antenna.

[okantex]

sorry , I did not understand.
on antenna amplifier addition.. C9 is connected to 4k7 pot's middle leg. I already disconnect it to disconnect antenna from sensor stage..
after seeing Null ( 0 V ) on sensor stage output ( on IC1A 's pin 3) , I will connect antenna.

what do you mean by calibration.. the calibration on field ?
cause your sentence " this is to restore the original conditions without the amplifier antenna." I am confused.

because during calibration of sensor stage.. you already write in HELPs file..to disconnect antenna.
if I connect C9 to Pots middle leg.. and just detach the telescopic antenna.. then I may receive field effects from bobbins.? but on the otherhand it may be better to calibrate the pcb with this disturbances too.

so , what should I do step by step

1. connect pot to C9
2. disconnect just telescopic antenna
3. decrease value of C13 and C14 , 560P to 470P
or 3th start replacing transistors

[FrancoItaly]

The initial calibration is done in the laboratory, therefore C9 is connected to the stylus antenna, the sensor stage output must always be present (even without phenomenon) and the optimal value is between 4 and 6V, to achieve this follow my helps .txt. When you have obtained the required values, you can connect the antenna amplifier, but it would be better to first try the original version in the field.

[okantex]

c13 and c14 ...I replaced 560p to 330p ,then to 100p then without any condansator..but all the time output is around 7V ..without cristal

[FrancoItaly]

As I said before, the sensor stage is the critical part of my lrl, which was originally an rf sniffer that oscillated in my realization and I realized that it worked like lrl. Since I realized that reproducing this self oscillation in other specimens was very difficult I designed an oscillator independent from the rest of the circuit. I think that if your lrl oscillates without connections with the quartz oscillator and with reduced gain almost certainly the defect consists in the pcb. Use a pcb only for the sensor stage with the lower face connected to ground.

[okantex]

pcb is okay..no cuts or no short circuits.. but I will build new pcb..
I am doing same of Walkman's pcb...it is already proved itself by videos..

[FrancoItaly]

Well, however, it can happen that (as in every pcb) the connections are exact but that there are parasitic couplings between two tracks that are important in the sensor stage which has a very high gain.

[okantex]

hi
while getting close to end of second pcb..
I want to ask a question..
When I build my first zahori...I burned IC ..I think it was 2N35.. I realised that it was because of high voltage line close to my house
since the voltage is too high..on my outputs ... can it be because of AC high voltage
did you have any experience of HV..

Certainly high voltage lines affect electronic instruments but also the human body.
For the setup of my lrl it is better to do it far from this line.

The Last video

the same target

https://www.youtube.com/watch?v=BQ3aaN044MA

enjoy it.
Here in this video you can clearly see, in the direction of izmiriy passes the road. And you can see how the bus rides. It seems that there the power line is going there. I think you are catching not a phenomenon, but the interference of passing vehicles (discharge on spark plugs). But from a very long distance.

[liudengyuand]

Obviously no one has ever succeeded, it can't detect metals, why is there anyone doing it?

[Morgan]

If the amplification of the lrl is too large, in addition to the compass effect there is also the sky effect, i.e. lowering or raising the lrl you have a signal, the two effects can be combined making it impossible to use. The lrl is a directional instrument, the maximum sensitivity is proceeding from north to south, the minimum is proceeding from south to north and proceeding from east to west and vice versa the sensitivity is medium. Furthermore, approaching the target, the signal increases but cancels right on the vertical where the target is buried. I find it difficult to believe that a target at 500 m can influence my lrl, to be true it should behave as described above, i.e. approaching the target (i.e. at 500m) the signal first weak and then increasingly strong until it decreases and cancels over the target (500m ahead). My lrl like almost all the others ultimately reveals an electrical or electromagnetic signal and therefore is subject to many disturbances.

yes, most of times the PHENOMENON can be located only in two lines ,see the video,the gold ring was found only Nort to South and West to East, the digging tool is point to south direction, in the video is doing the pinpoint work

the images show the 3 frequencies optional for the PDK-2.3 , as I remember explain very well how to install this in PDK single frequency.

[Arthur]

Hi friends, as Franco said, this signal is stronger than the north, and tracking should start from the north. As you approach the target signal, the signal turns on, so do the same from the south. If the target is deep, you are in the line from north to south, ie two points, half the distance between the two target points and half the distance of the approximate target depth, good luck.

the scheme is in my first post where there is the photo, I post it here again with the value of the components. However, I do not recommend not making it, it is too critical to work in self-oscillation, for this reason I made the version with the quartz oscillator. I post also here too.

Thank you,l"am build this 5mhz lrl,output voltege is 7.7v,this lrl is ok?

No, it is better in the 4-6 volt range, otherwise if the amplitude is too high it would be almost insensitive, in fact if the amplitude is already normally at maximum it could not reveal a further increase.

[Sreekumar]

What should i do next?

[FrancoItaly]

What should i do next?

The purpose of C6 is to adjust the gain, you can try acting on C6, if it is not enough increase R5 put 1.2 K or 1.5 K.

[Sreekumar]

C6 variable capacitor equalent other motheds

[FrancoItaly]

C6 variable capacitor equalent other motheds

The aim is to decrease the gain of the stage in order to have a stable oscillation but without distortion. The gain depends on several factors, the beta of the transistors, the resistors and the emitter capacitors.
The triggering of oscillations is due to parasitic capacities and is normally an unwanted defect but in our case we try to get it. As it is a bit laborious I thought of an external oscillator and a double-sided pcb with a face connected to ground in order to avoid self-oscillation. Following the help I provided (helps.txt) you get an optimal functioning.

Thank you brother,god bless you.

Hello

Where is the problem

My lrl (like everyone else) only works with metals that have been buried for at least a few weeks or months. It is necessary to have a test field.

If at the output of the sensor stage there is a stable signal between about 2 and 5V (DC signal) and touching the antenna the signal decreases even slightly, then the lrl is ready for outdoor tests. It should be borne in mind that there are many sources of false signals inside homes that should not be taken into consideration.

[ali02]

Hi dear Franco I put between Tr1 and Tr3 value of capacitor 1 ..to. 3 pF is good

But on the DC output is between 7 and 9.88V and not 2 to 4V. Yes oscillation is

I put that later because now I have problem with ISIS.

I don't know how to give you the answers to what you ask me. I have used my lrl very little in actual research. I assume that, as with other types of lrls, the depth can also exceed one meter, but it depends a lot on how long the metal has been buried. These days I am trying some modifications that significantly increase the sensitivity.

I post my original lrl, the antenna amplifier and pcb by Dream man, but for me it's better a single pcb for sensor stage. Before connecting antenna amplifier it is necessary to fine-tune the original version. I don't think this is an ion amplifier and the antenna is needed.

Yes it is, a further improvement that I am working on is to tune L1 / C10 on a harmonic of the quartz oscillator. To do this, you need to find different frequencies. I attach a new display stage that allows for better tuning.

The "phenomenon" is very complex and still unknown to mainstream science. There are other types of lrls that work with principles and frequencies different from mine, for example Alonzo PD with coil and ferrite or Infrared and ultraviolet. In my case the whip antenna presupposes the existence of an electric or electromagnetic field.
